Satellite positioning tracking systems to apply to high-precision positioning and autonomous driving with Super Formula at 290 km / h

On 14 December 2020, NTT DoCoMo will conduct a demonstration experiment using high-precision GNSS (general term for satellite positioning systems) to position the position of a vehicle traveling at a maximum speed of 290 km/h with an error of approximately 10 cm. Success Announced. The company intends to apply this to the autonomous driving of cars and railways, which requires an accurate understanding of the current situation.

Difference in course taking between two drivers based on position information by high-precision GNSS

The demonstration experiment was held at the “2020 All Japan Super Formula Championship Rounds 5 and 6” at the Suzuka Circuit (Suzuka City, Mie Prefecture) from December 4 to 6, 2020, where the “DOCOMO TEAM” racing team is DOCOMO’s main sponsor. We worked with NTT and “DANDELION RACING”. To determine the running position in real time, a GNSS receiver connected via an LTE line was installed in the team’s racing car.

When comparing the GNSS receiver position data with the passing position of the time measurement beacon installed in the circuit, it is said that the positioning was possible with an error of approximately 10 cm. It has also been found that 96 percent of the running time allows for high-precision positioning.

For racing tactics, the precise running trajectory gained from the positioning data can also be used. The same team’s Kiyoshi Muraoka said Because the two drivers (Naoki Yamamoto and Nirei Fukuzumi) can visualize different course taking (running trajectory), it will lead to the realization of which course was better after the race.” DoCoMo is working with the same team on different demonstration experiments, such as improving the quality of communication when moving at high speed.
